Specification of Letters Patent.

Application filed May 11,1907. Serial No. 373,064.

To all whom it may roncm'n? Be it known that 1, He WARD M. PARKS, acitizen of the United States, and a resident of the city of Fitchburg,county of Worcester, and State of Massachusetts,

have invented certai n new and useful Improvements in PipeJ-langers, ofwhich the following is a specifidation.

This invention relates to pipe hangers for supporting pipes or coils.

An object of the invention is to provide a cheap and efiicicnt pipehanger construction which may be made up in mill lengths for stock fromwhich any suitable length may be cut off to accommodate a particularnumber of pipes to be suspended.

A further object of the invention is to provide a cheap and ellicionthanger which may be suspended at various desired intervals throughoutits length according to the number of pipes to be carried and accordingto the accessibility of suita bio means to which suspension rods may besecured.

A preferred embodiment of the invention is illustrated in theaccompanying drawings, which form part of this application, in whichlike numerals designate corresponding parts, and in which,-

Figurc 1 is a perspective view showing a section of the pipe hangerconstruction provided with two suspension rods and supporting threepipes; Fig. 2 is a vertical section through line 2-2 of Fig. 1 showing apipe in side elevation: Fig. 3 is a top plan of a section of the pipehanger construction; Fig. 4 is a side elevation of a section of the pipehanger construction; and Fig. 5 is a roll of the pipe hangerconstruction showing a mill or stock length.

Referring now mo ro in detail to the drawings, 1 and 2 designate twocontinuous complementary strips of sheet metal, preferably wrought orpressed steel. Along the upper edges of the strips 1. and 2 is provideda series of curved pipe holding notches 3.

At each side of each notch there is preferably provided a semi-tubulartransverse rib or corrugation 4 for the strip 1 and 5 for the strip 2.The strips 1 and 2 are preferal'ily riveted one to the other by rivets 6adjacent the semi-tubular ribs so that said ribs are secured injuxtaposition as shown particularly in Fig. 3, and so that the notches 3overlie one another and together form suitable receptacles for pipes.The opposite ribs 4, 5, together form a tubular portion or receptaclefor suspension rods such as 7 and 8. The suspension rods 7 and S, asshown in Fig. 1 project through the tubular receptacles and are providedat their lower extremities with nuts 9 and 10 to support the pipehanger. The

upper ends of the suspension rods 7 and 8 may be providod with hooks orthe like 11 and 12 for engaging eye bolts or other suitable suspendingmeans wh ich may be secured to a wall or ceiling beam.

The supporting rods 7 and 8, etc., which extend vertically, engage'thetubular receptacles formed by the ribs 4 and 5 throughout their entireextent and serve to hold the pipe hanger in substantially a verticalplane so that the full shearing strength of the strips 1 and 2 is usefulto support the weight of the pipes 13, 14, 15, etc.

In practice, it is found that pipe hangers made up in standard lengthsin cast metal to accommodate given numbers of pipes are not satisfactoryas each installation is likely to require a different number of pipesfrom' a former. \Vith the present invention, a roll 16 of the sheetsteel pipe hanger construction, as shown in Fig. 5, or a long milllength not necessarily in the form of a roll, may be kept in stock andwhenever a pipe hanger for a given installation is desired, the exactlength providing the required number of pipe holding notches may be cutoff and used.

The tubular receptacles provided at each side of the pipe receivingnotches, as indicated in the figures, are also very desirable as it isfrequently found that end suspension rods cannot always be used for lackof something to which to secure their upper ends. In the presentconstruction, suspension rods may be provided either at the ends, asshown in Fig. 1 or between the pipes 13 and 14 or 14 and 15. Also when along pipe hanger is used, it is frequently desirable to providesuspension rods both at the ends and intermediate the supported pipes,the particular localities depending upon existing circumstances. 7

Although a preferred embodiment of the invention has been illustratedand described, it is to be understood that modifications within thescope of the invention are contemplated.
